I think the GP referred more to those people who write down a lot but (almost) never refer to their notes or review them. For many people, after several years they will have a giant repository of hundreds or thousands of notes with very poor organization and the value decreases rapidly because they can't find anything anymore.
That’s true for me, but I’ve found that the easier and more streamlined my note-taking apparatus is, the less effective it is at helping my memory to congeal. I just keep a scrap of paper handy and jot stuff down occasionally. I’m trying out a Techo this year, so that’s a step more sophisticated. Handwriting seems to be the important bit for me.
I've found hand written notes to be important for me. I have dozens of filled notebooks in my office that I've never read again. The act of writing things down by hand helps to lock them in my brain. I've tried to take notes electronically, but I find I don't retain as much. Something about pen to paper helps me retain information.
True, up to a point. Taking one of the sibling comments as an example, by the time you have accumulated 20.000 notes the older notes will definitely start getting "crowded out" if you don't review them.
I think there are two types of memories, and two types of notes as a result -- there's specific figures where you might only have to remember it for a couple days, and the exact value might be important, so that note/memory's value is very temporal. Then there's the stuff like problem solving strategies, where hopefully that information is integrated into your brain at some deeper level. The former might never be looked at again if it turns out you don't need the figure, the latter might never be looked at if the integration was successful.
Not really - I have old notebooks of notes that I havent thrown away but I also dont review - they are just musings and historical records, really you could throw them out but I like sometimes paging through them and looking at stuff I did.
New notebooks get a label on the front and only when they are full or I retire that hobby do they go in the notebook bin.
